In the course of screening for biological active compounds from microbial origins, various strains were isolated from roots of Mimosa pudica using standard dilution agar plate method. One isolate was selected for further studies of bacterial anti-fungal properties. It was designated MSSP and identified as Burkholderia sp. by many biological characteristics such as carbohydrate utilization, bioc...

ABSTRACT Pathogens of the Straminipile genus Phytophthora cause significant disease losses to global cocoa production. P. megakarya causes significant pod rot and losses due to canker in West Africa, whereas P. capsici and P. citrophthora cause pod rots in Central and South America. The global and highly damaging P. palmivora attacks all parts of the cocoa tree at all stages of the growing cycl...

ABSTRACT Vegetable crops are exposed to constant infection by numerous diseases, including those caused the oomycete Phytophthora capsici. This microorganism is a polyphagous plant pathogen, capable of infecting dozens species, cultivated plants and weeds. The aim this review address topics related etiology symptoms diseases (leaf blight, root rot, crown rot fruit rot), as well integration appl...

Salt and osmotic stress seriously restrict the growth, development, productivity of horticultural crops in greenhouse. The papain-like cysteine proteases (PLCPs) participate multi-stress responses plants. We previously demonstrated that salt affect protease 15 pepper (Capsicum annuum L.) (CaCP15); however, role CaCP15 is unknown. Here, function regulating resistance was explored. Pepper plants ...

This study investigated the expression pattern of genes encoding for a basic PR-1 protein, a basic beta-1,3-glucanase, a peroxidase, and a sesquiterpene cyclase involved in defense responses in three pepper cultivars with different levels of resistance to Phytophthora capsici. All genes were up-regulated in infected stems of the pepper cultivars, with expression being detected 8h post-inoculati...

Xestoquinone and related metabolites (the xestoquinone family) occur in marine sponges and are known to show a variety of biological activities. In this study, the first comprehensive evaluation of antifungal activity was performed for xestoquinone and nine natural and unnatural analogues in comparison with their cytotoxicity. The cytotoxicity against two human squamous cell carcinoma cell line...

The bacterial strain T-9, which shows strong antifungal activity, is isolated from the soils of Samcheok, Gangwondo and identified as Paenibacillus kribbensis according to morphological and taxonomic characteristics and 16S rRNA gene sequence analysis. The P. kribbensis strain T-9 strongly inhibits the growth of various phytopathogenic fungi including Botrytis cinerea, Colletotricum acutatum, F...

A Bacillus velezensis strain from the rhizosphere of Sporobolus airoides (Torr.) Torr., a grass in central-north México, was isolated during a biocontrol of phytopathogens scrutiny study. The 2A-2B strain exhibited at least 60% of growth inhibition of virulent isolates of phytopathogens causing root rot. These phytopathogens include Phytophthora capsici, Fusarium solani, Fusarium oxysporum and ...

Entomopathogenic bacteria Xenorhabdus spp. produce secondary metabolites with potential antimicrobial activity for use in agricultural productions. This study evaluated the inhibitory effect of X. nematophila TB culture on plant pathogens Botrytis cinerea and Phytophthora capsici. The cell-free filtrate of TB culture showed strong inhibitory effects (>90%) on mycelial growth of both pathogens. ...
